The trunni(in-castings are journaled in bearing" bushings .17, 18, each of which is a section of a sphere. These bushings are mounted in corresoonrlingly formed supports 19, 20, on the bearing members 6, 7, so as to be capable of movement in the mannor of a ball audsoc Gt joint. Parallel with toe axis of the barrel is a counliershaft 21, mounted in ball-and-socltet bearing. 22 of the same type as those employed with the barrel. i i one end of the shaft is a pinion meshii'ig with the gear 16 to drive the same, and at the other endof theshaft is a pulley 25 for connection with source of power. i From the foregoing it will be evident that either bearing member 6, 7, may be raised or lowered vertically relatively to the other. such adjustment the spherical bearing bushings of the barrel and the countershaft have a slight movement of rotation about their horizontal diameters, as is shown in the case of the barrel bushings in Fig. At the same time the bearings at the elevated end move axially a slight distance on the jOllIIlulS which they support, to accommodate tl'ieniselves to the slightly increased distance between them and the correspond i'ug bearin s at the other end of the appa ratus. In the machine illustrated the vertical justment is effected at the inlet end, v means of vertical adjusting screws 26, 27, working in nuts 28, 29, fixed between the I-beams t, 5, and extending into contact with the foundation extension 2. When the inlet end. has by this been raised as far as desired, as will be more fully explained hereinafter, suitable blocks 30, equal in height to the space between the I-beams and the foundation, are placed between the same, and the binding bolts '31, the nuts 32 of which. are set in recesses in the foundation, are tightened up, thereby clamping the parts firmly together and securing the hearing members 6 in rig d connection with the foundation. The ad usting screws 26, 27, may then be removed, if desired.

The operation of the mill is as follows: The barrel being rotated by power applied 'to the driving pulley 25, the ore or other material to be disintegrated is fed into barrel through the inlet trunnion 10, with or vithout a: current of water, as may be (9- sired. Inside the barrel the pieces or lumps of ore are subjected to impact and attrition among themselves and the grinding or crushing bodies if such are used. As the lumps of ore are broken up the pieces there of pass toward the outlet, and finally reach ady the outlet trunnion 9, where they are discharged. The fineness of the material discharged depends, other thiugs being equal,- in general upon the inclination of the barrel with respect to the horizontal. If ithe axis of the barrel be horizontal the maximum fineness will be produced, and the higher the inlet is raised relatively to the As previously stated, the barrel in the preferred form of mill consists of two cones with an intermediate cylindrical portion. as is shown diagrammatically in Fig. 4. The pitch of the outlet cone, 11, may bevaried considerably, but in practical use of the invention acone with a slant of about 30 relative to its axis has been found to give excellent results. The inlet portion, 12', may also be varied, from a cone to a mere plate as shown at 12 in Fig. 5, but its pitch with respect to its axis should be greater than that of the outlet cone. \Vith a 30 outlet cone very satisfactory results have been obtained with a (30 inlet cone. The cylindrical portion 13 affords space for a considerable number of large crushing bodies, and for that reason is desirable, particularly where hard mater'als are to be reduced. In the mill illustrated the cylindrical part is about onefourth as long as its diameter, but the-length may be varied, being made longer or shorter according as the material on which the mill is to work harder or soft-er. In general, however, the cylinder should not be longer than its own diameter, as beyond that size, approximately, even with the hardest ore or other material the power required to revolve the mill, with the large amount of crushing bodies necessary with so large a cylindrical. portion, exceeds the gain or advantage which would otherwise flow from having alarge cylindrical portion.

The details of construction illustrated in Figs. 1, 2, and 3 may also be varied without departure from the spirit of my invention. However, as before stated, the construction shown in the figures named has been found to give very satisfactory resultsin practical use. What I claim is: 1 1. In an apparatus for disintegrating ore and other material, in combination, a barrel or drum having axial inlet and outlettrum' nions. bearing members for the trunnions, each having a. cylindrical inner surface surrounding a trunnion and a spherical outer surface, supporting members having spheri cal inner surfaces to fit the said bearing or drum, having axial inlet and outlet trunnions. ball-and-socket bearings for said trunnions, separate ,means for elevating either trunnion independently of the other, and means alongside said'drum elevated simultaneously 'with the elevation of said drum for operating the latter on its trunnions.

3. In an apparatus for disintegrating ore and other material, in combination, a conical barrel or drum having axial inlet and outlet trunnions, lmll-and-socket bearings therefor, a shaft alongside of the barrel or drum, ball-and-socket bearings for said shaft, means for raising and lowering the shaft and'barrel bearings at one end of the apparatus relatively to the bearings at the other end,. a gear on the barrel or drum, a pinion on the shaft meshing with said gear, and a driving pulley on the shaft, as set forth.

-l. In an apparatus for disintegrating ore and other material. iii-combination, a conical barrel or drum having axial inlet and outlet trunnions, ball-andsocket bearings for the trunnions, means for raising and lowering one of said bearings relatively to the other, a gear on the barrel or drum, a pinion meshing with said gear, and means for rotating the pinion, set forth.

5. In an apparatus for disintegrating ore and other materials, the combination of a barrel or drum rotatable about its longitudinal axis and having axial inlet and outlet trunnionsa a supporting foundation, transverse supports mounted on the foundation at the ends of the barrel, tiltable bearings for the trunnions mounted on the transverse supports, adriving shaft parallel to the axis of the barrel and connected with the barrel to rotate the same,'bearings for the driving shaft mounted on said transverse supports and in fixed relation to the said barrel hearings. and means for raising and lowering one of the transverse supports.

ln testimony whereof I affix my signature in the presence of two subscribing witnesses.
